What is the National Highway Construction Cost Index?
The National Highway Construction Cost Index (NHCCI), published quarterly since the first quarter of 2003, uses a database of successful bids on state highway projects that includes quotes on the specific items in the projects. The NHCCI measures from the perspective of the buyer (e.g., the state). It includes the costs of material and labor as well as profit and overhead. The average price charged is calculated for each item in each state, and these price changes are then combined into a national index based on a market basket of items.
